A DYNAMIC DATABASE FOR GEOCHEMICAL AND MINERALOGICAL DATA FOR SOILS OF THE CONTERMINOUS UNITED STATES COLLECTED FOR THE USGS GEOCHEMICAL LANDSCAPES PROJECT
The results of the chemical and mineralogical analyses will be available to the public as a set of three tables (0-5 cm depth, soil A horizon, and soil C horizon) downloadable from the USGS Mineral Resources On-Line Spatial Data website (mrdata.usgs.gov). All tables have an identical structure to allow the users to readily combine them into larger files.
A .kml file that opens with Google Earth®, ArcGlobe®, or other mapping software packages will also be available. This file greatly facilitates the visualization of the data, which then can be combined with other digital layers such as geologic maps or mineral occurrences. A digital geochemical and mineralogical soil atlas will be published on-line for the conterminous United States, with interpolated maps of the distribution of the analyzed chemical elements and the major minerals found in the soil samples as well as descriptive statistics and plots.
